Electroplating setup for Hobbyists

I was tasked to electroplate a few hundred silver rings. I bought some components online and 3D printed the rest. 1- Silver solder the ring rack. 2mm diameter pure copper. Leave one side open to allow the ring to slide onto the rack. 2- 3D print the anode holder as four separate parts, to be super glued or methylene chlorided later. 3- The opening slot is hard to widen, even with a Dremel high speed tool. Modify the 3D printable parts prior to assembly and printing. 4- This is designed for Corning 500ml No. 1003 beaker.
